    One clarification please help me out in this

    Piston diameter: 125mm
    Piston rod diameter: 90mm
    Weight of the object to be lifted : 3000kg
    Hydraulic oil used : HLP46
    Required stroke length is 1meter

    My question is what would be the approximate time (in sec) taken by the hydraulic cylinder to get the required lift of 1meter.


    I dont have not even a single idea in this concept.. Please help me out in this

    What is the efficiency of the hydraulic pump?

    The speed of the piston is directly proportional to the capacity of the hydraulic pump
    example:
    D = 125mm
    A = (0.125 * 0.125) * PI / 4 = 0.0123 m2
    If the oil flow rate of 1 l / s Q = 0.001 m3 / s
    and the efficiency of the actuator = 0.95
    the speed v = 0.95 Q / A = 0.001 * 0.95 / 0.0123 = 0.0772 m / s

    So time to raise about 1 m is t= 1/0,0772 = 12.9 s
    Are you sure? This action cannot be undone.
